Washoe County is reporting its highest high school graduation rate in history, with a more than 3% increase last school year. Reno Public Radio's Michelle Bliss has the details.

Overall, the state department of education is reporting Nevada's preliminary graduation rate as 70.9 percent for the Class of 2015, up from a flat 70% the year before. That uptick is largely because of improvements within the Clark County School District, one the of largest in the country.

Nevada's attorney general says the Washoe County School Board violated the state's open meetings law when it ousted Superintendent Pedro Martinez.

According to the complaint filed in district court on Tuesday, the school board broke the law in at least six different ways when trustees questioned Martinez about his status as a certified public accountant and then fired him.
